Model: Mercedes Classe B W245, MK 1 - Years 2005-2011
Part: Spark plugs

Removing the spark plugs from a Mercedes B-Class? Remove the spark plugs from inside the engine compartment. Lift the front bonnet and secure it, then disconnect the battery terminals. Remove the soundproofing panel covering the engine if access is difficult. Remove the coils from the cylinder head or the side; then unscrew the spark plugs with a socket spanner and pull them out of the cylinder head. Take the new spark plugs and guide them with the extension of the socket spanner into the cylinder head, tighten them, and connect the power coils to each spark plug with new leads. Test their correct operation. Close the engine compartment after maintenance.
